How to Destroy a Boiler -- Part 1

Trapped moisture quickly becomes steam and causes the refractory to spall as the steam escapes. The standard warm-up curve for a typical boiler does not increase the boiler water temperature over 100°F per hour. It is not unusual for a continuous minimum fire to exceed this maximum warm-up rate.

Safety-level controls protect the boiler against an excessive draw-off of steam. As the load decreases, the boiler maintains its maximum firing rate and allows the extra water to return to the normal (higher) working water level and the higher working pressure regained. 23.1.12 Accumulator. This may be likened to an unfired boiler.
